I have planed to build this frame for cinematic style or indoor video.
One of my frineds have had problem with 3inch with full gopro(around 120g) because motor get extremly hot over 1min flying. It's not super fast and acro style.
So i found this frame and motor. i compared between 1507 or 1408 motor(my friend's) and my motor (FPVCycle).
FPVCycle 2203 is not hot. it's just warm when i do acro-freestyle. Flight perfomance is not ultra super fast response such as 5inch but it's great handling with cinematic shot. I'm freed from worry. I like this pancake-shaped motor.

The frame is just normal. i just only ordred frame because i have 3D printer and i can make duck by my printing.

The motor is now super cool when i fly over 3 min also i reduced weight as i can do. Yes, i''m not doing acro-freestyle with this quad because it's made for cinematic. For this purpose, it's so great

In disadvantage, if the wind is strong, this quad is not quit flight perfomance. It' heavy weight(AUW is around 490~530 g) so i use reelsteady go with gopro 6 when the wind is too strong. Now i'm working on duck re-design for wind condition. The main thing is weight. Also, i tried 3.5inch prop. The flight perfomance is better than 3"

Anyway, I'm happy to get and build this quad.

Thanks!

I use still analog system so VTX is just 1 g so i can redue the weigh of AUW a lot!
It's around 490 g~ 530 g. it depends on what battery is used.

i recommend battery and prop:

4s with 3-blade outside
3s with 5-blade indoor (which is quiter than 4s 3-blade)

Build video (plz, turn on ENG subtitle)

After build and flight video (waterfall shot is not 3inch. it was 5inch quad)
